Situational Judgment and Decision Making

What this domain tests

Situational Judgment and Decision Making tests how you prioritize safety, apply legal authority, communicate, de-escalate, request resources, and document decisions in realistic police scenarios.

Core rules

  • Protect life first, then officer safety, then property; use the least intrusive effective action.
  • You may act only within legal authority; suspicion must be articulable, not a hunch.
  • Give clear, calm commands and explain the reason for the stop when practical.
  • Filming or observing from a safe distance is generally not, by itself, interference; address actual obstruction.
  • Escalation should be proportional and reversible; request backup or a supervisor when control is uncertain.
  • Document the facts and the reasoning, including warnings and de-escalation attempts.

Worked example

A trooper stops a car for expired registration. The driver begins yelling that the stop is unfair, and a passenger steps onto the sidewalk and starts filming. Traffic is light, and no weapon is visible. Best initial action: keep a safe distance, use a calm tone, state the reason for the stop, ask the driver to lower his voice, and tell the passenger to remain at a safe distance. Do not grab the phone or order filming stopped unless the passenger physically interferes. Request backup if the driver continues to escalate. Reasoning: the response addresses safety and the legal basis for the stop without turning a registration violation into a confrontation.

Traps that cost marks

  • Escalating with threats or unnecessary force.
  • Ignoring a medical or mental-health crisis.
  • Confusing disrespect with a crime.
  • Failing to document warnings or de-escalation.
  • Searching without consent, warrant, or another legal basis.
